SPECIFICATION forming part of Letters Patent No. 558,046, dated April14, 1896.

Serial No. 1 4,9 5 0. (No model.)

To all whom it may concern.-

Be it known that we, JOHN H. DALE and HARMER DENNEY, citizens of theUnited States, residing at New York, in the county and State of NewYork, have invented certain new and useful Improvements in Machines forMaking Envelops, of which the following is a specification.

The object of this invention is to produce, economically and rapidly,envelope of a special style herein described and illustrated;

. and the invention comprises certain improved organizations claimed,whereby a continuous strip of paper from a roll is printed, its edgescut to the desired contour to form the subsequently severedenvelop-blanks, and the blanks folded and gummed to complete theenvelops.

In the accompanying drawings, which illustrate our invention in the formbest known to us, Figure l is a side elevation; Fig. 2, a verticalcentral longitudinal section on the line 2 2 of Fig. 3 Fig. 3, a planview; Fig. 4, a cross-section on the line 4 4 of Fig. 2, looking in thedirection of the arrow; Fig. 5, a cross-section on the same line,looking in the opposite direction; Fig. 6, an elevation of the foldingend of the machine; Fig. 7, a view, partly in elevation and section onthe line 7 7 of Fig. 2, looking in the direction of the arrow; Fig. 8,an enlarged detail view of the device for forming the first transversefold z. e. the fold of the closing-fiapwhich is subsequently folded outagain when the second transverse fold of the body is made and one sideof the body is pressed upon the gummed faces of the folded side flaps;Fig. 9,. a similar view of the devices for forming the second transverseor body fold; Fig. 10, a view of the blank with all folds opened, thelines of the folds being indicated by dotted lines. Fig. 11 shows thecompleted envelop. Fig. 12 is a detail plan view, and Fig. 13 atransverse sectional view, showing the blank perforating and severingdevices and some parts contiguous thereto; Fig. 14:, a longitudinalsection on the line 14 let of Fig. 12; Fig. 15,

a detail plan view illustrating the carryingtapes and the rolls throughwhich the envelop is passed while the closing-flap is being gulnmed, andFig. 16 is a detail perspective viewof the gumming-wheel and two of therolls through which the envelop is passing while the closing-flap isbeing gummed.

The frame of the machine is marked A, and mounted therein is adriving-shaft B, equipped with a pulley driven by a belt B. From thisshaft the mechanisms for operating upon the paper strip to finallycomplete the envelop are driven by suitable gearing, the direction ofrotation being indicated by arrows, and by means of a counter-shaft Band miter-gear connections the printing devices and the device forforming a longitudinal row of perforations in the edge of the continuous paper strip are actuated in proper time from the shaft B. Theroll of paper (1 is mounted on a spindle supported in brackets at oneend of the machine, and the paper strip (which is marked 0) passesthence over a guide-pin or small roll Z vertically between theperforating-rolls O, by which the row of perforations c is formed in theedge of the continuous strip. These perforations are designed tocooperate with a sprocket or pin wheel to properly guide and time thepaper strip at a subsequent operation, as hereinafter described.

The paper strip thence passes between driven feeding or drawing rolls 0one of which has its bearings at the angles of two bell-crank levers Cand the projecting arm of one of said levers is connected by a spiralspring 0 with the frame, so that a proper pressure or grip upon thepaper strip may be maintained. From these feed-rolls the strip passesbetween the impression-cylinderD and type-cylinder D of a printingmechanism of usual construction, the desired printed impression beingmade upon that part of the strip that subsequently forms the back andfront of the completed envelop. Thence the strip passes vertically overa roll I) and then horizontally over a drying-plate D heated beneath bygas-jets D or in any other suitable manner, the length of thedrying-plate and its temperature being such as to properly dry the ink.The drier may be dispensed with, even when the machine is run at topspeed, where quick-drying inks are used. The strip .7 then passes over-aroll D and down around a roll or pin D, and thence upwardly to a pin orsprocket wheel E, whose projections or pins coincide With and enter theperforations c in the edge of the strip and insure the feed of the stripto the blank-cutters in proper relation to the printed matter impressedupon the strip. The strip then passes around an adjustable guide pin orroller E, adjusted by a handle 6 and secured by a set-nut c, (thisadjustment being provided to also insure the proper relation of theprinted matter and blank-cutting devices,) thence between pairs ofcutting-rolls F F, so shaped and acting as to cut the proper marginalcontour of the two edges of the strip, as seen in Figs. 3 and 10, theperforated edge of the paper being cut away and the side notches c andside flaps c being formed at each edge. The strip then passes up betweenedge-folders F F, (analogous to ordinary hemming-folders and of usualconstruction,) by which the side flaps c are folded over on the strip,as seen in Fig. 3. From these side folders the strip passes over a rollf, and thence horizontally between feed-rolls, the bottom one G of whichis driven, and the upper one G is supported by springarms 9, at thispoint the side flaps being already folded over, as stated. The stripthen passes between blank perforating and severin g devices, which maybe constructed as follows: A frame H slides horizontally in ways It onthe main frame and carries below the strip two parallel transverse rowsof female perforating-dies H and a shearing or cutting edge H and abovethe strip corresponding transverse parallel rows of perforating punchesh and a cutter ]L2. The cross-piece H carrying these upper parts, issupported at each end by uprights II, that slide vertically in thel1orizontally-reciprocating frame H, and have each a projecting pin orsmall roller that travels in a horizontal groove in the upper end of abar H sliding vertically in'ways in the main frame, and the bars H H andcross-piece H are all moved downward by cams on shaft B, into which pinson H work (see Fig. 2) to draw down the cutter and perforator at theproper time to sever a blank and cut in the succeeding blank the tworows of perforations c c, Fig. 10, one row on each side of the line onwhich the closing-flap of the envelop is to be folded. These cuttingdevices are reciprocated horizontally by cams I I on a shaft 1, and theforward movement is at the same speed as that at which the paper stripis traveling. The blank thus severed is seen in Fig. 10, except that theside flaps e have been folded over. The severed blank now passes forwardbetween rollers K, and the closing-flap passes over the foldingrolls 1At the proper time the cam M moves the folding-blade M downward, and theflap is folded between the parallel lines of perforations, the foldededge passing down between the rollers I and K.

N is the paste-box, N the roller running therein, N thepaste-distributing rolls, and N the dabbing or paste-applying rolls,which are mounted on arms N projecting from a rock-shaft N, that carriesan arm M, acted upon by a cam n to at the proper time throw thepaste-dabbing rolls N against the exposed faces of the folded sideflaps, the blank being held up against the dabbing-rolls by a roller 9%.The blank now passes down until the line for the transverse body-foldcomes opposite the bite of two folding-rolls 0. When a foldingblade 0,supported at each end by a rod 0 actuated by a cam 0 is drawn forward,the body of the blank is folded transversely and the folded edge pressedbetween the rolls 0. The width of this blade is less than the dis tancebetween the edge of the inwardly-folded closing-flap and transversebody-fold made by the blade, and consequently, as the cam causes theblade to recede, the blade catches the edge of the folding-flap anddraws or folds the flap out. The side of the body has in this foldingoperation been pressed against the pasted flaps and that portion of theenvelop completed.

The closing-flap is yet to be gummed or pasted, dried, and folded down.From the folding-rolls O the partiallycompleted envelop now passesbetween tapes P P, which carry it downward and turning it at rightangles delivers it upon a horizontal table Q, from whence it is drawnlaterally endwisc by a D'roll R and delivered to feed-rolls S S. Thenceit passes down between S and roll S under S and then up between S androll S While passing in this sinuous course through these rolls the lipof the closing-flap, which projects beyond the end of the roll S that issomewhat shorter than the rolls S S is gummed by a roll T, runnin gin apaste or gum box T, the flap being held up against the pasting-roll bythe roll 8. The curvature given to the flap of the envelop serves tostiffen it, so that it will properly take the gum or paste from the rollT. This construction is designed to prevent the application of gum tothe roll S which will be liable to occur if such roll projected to theedge of the envelop flap that is to say, we are enabled to apply thepaste to the extreme edge of the flap and avoid the fouling of thecarrying-rolls, and consequently the marring of the closing-flaps. Fromthe roll S the envelop passes between carrying-tapes U U and isdelivered to the bite of rolls V V, between which it passes downwardly,being directed by guides 12, and is delivered into one of a series ofpockets 20, formed by radial partitions w on a circular revolving frame\V. This table is driven step by step from the driving-shaft B by acrankand-pitman connection 10 actuating a pawl 10 driving aratchet-wheel 10 on a shaft 10 having a gear to, driving a gear w on theworm 10 that drives the wheel w on the revolving frame XV. The pockets ware closed at the bottom by an annular stationary plate or ring X, whichhas an opening X in it, through which the envelops are successivelydropped after having been carried through approximately one revolutionof the revolv ing frame, during which the gum on the lip of theclosing-flap has had opportunity to dry. \Vhen the envelop falls throughthe opening X, it is caught between rolls X X and thence passes betweenpairs of rolls X X and X X and during its passage between such rolls theclosing-flap is folded down by a foldingguide Y, and the now-completedenvelop is delivered into any suitable receptacle. The revolvingcircular frame is of course moved one step each time an envelop-blank issevered from the continuous paper strip.

The various shafts, gears, and belts and their directions of movement orrotation have been indicated, and it seems unnecessary to load thespecification with minute description of their specific connections,since the operations described may be accomplished by the mechanismshown or any other equivalent well-known devices.

In the completed envelop the two lines of perforations come oppositeeach other and are intended to afford a ready means of opening thesealed envelop by tearing the edge along the line of the perforations.
